About Relay

Relay is a free local harness for AI coding agents. You queue backlog tasks, each in its own git worktree, and the agent runs with a model you sign in to, such as Claude, ChatGPT or Copilot, or with an API key from providers like Anthropic, OpenAI, Google, xAI, DeepSeek, Mistral, OpenRouter or Amazon Bedrock. Relay itself never bills for tokens.

After a run, Relay executes your tests, lint and build again before any pull request is opened, learns from each run for the next one, and caps turns, tokens, time and spend. Sessions keep working when the terminal is closed and relay attach reconnects. Paid plans add unattended runs across many repositories and checks in fresh Relay sandboxes, and the team plan adds an organization baseline for CI checks. Installation is one shell command on macOS, Linux and WSL, and the source is not published.
